Abstract: 알켄, 이산화탄소, 및 [O] 기에직접결합된 2급또는 3급탄소원자를갖는알콕사이드로부터α,β-에틸렌계불포화카복실산염을제조하는촉매적방법이기재된다. 중간상 분리후 알코올부산물이증류제거된다. 상기방법은최소한의노력으로순수한α,β-에틸렌계불포화카복실산염을제공한다.

Abstract: A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt from an alkene, carbon dioxide and an alkoxide having a secondary or tertiary carbon atom directly bound to a [O-] group is described. The alcohol byproduct is distilled off after an intermediate phase separation. This provides pure α,β-ethylenically unsaturated carboxylic acid salt at minimum effort.
